A first winter Bonaparte's gull has been just north of Preston at Myerscough Quarry, pit 2, for two
weeks giving me the opportunity to visit the site for the first time. The bird was showing when I arrived with about 10 black-headed gulls and was feeding by picking invertebrates off the surface of the water.
This was
my ninth Bonaparte's gull in the UK and my third in Lancashire following birds at
Seaforth (1990) and Heysham (2013).
The underwing is diagnostic, much more white than the similar black-headed
gulls with just a thin black line on the trailing edge of the wingtips.
